The invention consists in the combination and arrangement of parts to behereinafter fully described in the following specification, pointed outin the appended claims and illustrated in the accompanying drawingswhich form a part of said specification and in which- Figure 1 is afront elevation of my improved leather cutter, with the table insection, taken on line 1-1 of Fig. 2. Fig. 2 is an end view of thedevice taken on line 2-2 of Fig. 1. Fig. 3 is a vertical sectional viewthrough the roll and guide and is taken on line 3-3 of Fig. 1. Fig. 1 isan end view taken on line dl of Fig. 1, with the roll and knife turnedhalf way around. Fig. 5 is a front view of an auxiliary roll sectionwhich may be connected to the main roll when a piece of leather ofexceptional width is under operation. Fig. 6 is a cross section on line66 of Fig. 5. Fig. 7 is a front elevation of the roll and knife in theposition shown in Fig. sand with an auxiliary guide secured to theshaft. Fig. 8 is a cross section taken on line 8-8 of Fig. 7. Fig. 9 isa front view of a modification of a portion of the guide. Fig. 10 is aplan view of Fig. 9.

Like reference characters indicate corre sponding parts throughout theseveral views.

My leather cutter comprises the base 1 which may be bolted as at 2 to asuitable table or support 3 and to said base 1 the standards 4, 4 arebolted that carry the shaft 5 on which the sectional roll 6, 6 iscarried and between and to the sections of said roll the knife 7 issecured, said knife being Specification of Letters Patent.

formed with the diagonally opposite relaadjustable guide 14 is arrangedand the same is provided with a transversely extending finger 15 held inposition by a pin 15 and said finger is formed with a lug 16 againstwhich one edge of the-leather strip, being cut, rides. The guide 14 isset upon the gage 10 adistance from the knife equal to the width ofstrip to be cut the leather piece is then manually drawn overthe rollagainst the knife, one edge of the leather riding against the lug l6 andthe entire piece of leather extendingfrom said lug laterally beyond theknife. The operator stands back of the roll or in a position with theroll be tween himself and the table and pulls the ,leather over the rollagainst the knife. The

operation ust described is the one employed to cut the leather intostrips of ordinary sizes.

To cut the leather into exceptionally large strips the roll 6, 6 isturned half way around or into the position illustrated in Figs. sand 7thus moving the knife edge 9 into operativeposition and disposing thegage 10 and guide 1a in inoperative position or back of the cuttingedge. A bracket 17 is placed between the nuts 13, 13 upon the shaft 5 tosupport the adjustable gage 18 provided with the sliding guide 19. Theguide 19 is similiar in every way to the guide 14 and is provided with afinger 20 similar to finger sections 21, 21 and said sections are formedwith lugs 22 in which the ends of a spring 23 are secured which springtends to draw the free ends of the sections 21 together.

A lug 2% depends from one section 21 and against said lug one edge ofthe sheet of leather rides, this edge being inserted be tweenthefreegendsof said sections. The opening 25in the one section 21 is toreceive the pm by Which it is secured to the guide 14:. WVhen'Widestrips of leather are standard 4; enters shaft 5 to normally preventrotation of the roll 66.
